SAFETY OAR-LOCK.

Specification of Letters Patent.

Patented Nov. as, 1916.

Application filed December 9, 1915. Serial No. 65,951.

To all whom it may concern:

Be it known that I, GEORGE W. ABM- STRONG, a citizen of the United States, residing at Salem, in the county of Marion, State of Oregon, have invented certain new and useful Improvements in Safety Oar- Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in oar-locks, and the object thereof, resides in providing a device which is adapted for permanent location in the gunwale of a boat and provided with means for instantly removing same therefrom.

The invention further contemplates a device of the character set forth having a portion of the oar retaining ring pivotally mounted, and which may be adjusted on its pivotal mounting, to allow for the insertion of the ends of the oars therewithin, means being provided for detachably securing the' ring sections together.

The invention consists of the novel features,-details of construction and combination of parts, which hereinafter will be more particularly described, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the drawing, forminga part of the application, Figure 1, is a side elevational view of my improved oar-lock, applied to a portion of the gunwale of a boat. Fig. 2, is a central vertical sectional view. Fig. 3, is a similar view with the locking arm open. Fig. 4, is a plan view of the locking plate.

Corresponding and like parts are referred to in the following description, and indicated in allthe views of the drawings, by the same reference characters.

Th numeral 5, designates a locking plate formed with an enlarged central'portion 6, which is apertured at 7 for the spindle 7 of the oar-lock 8, and providing a bearing for the flange portion 9 thereof. The plate 5 is provided with end ears 10, which are apertured at 11, for the fastening attachments 12, by which the said plate is secured to the gunwale 18, of a boat. The spindle 7 is rotatably mounted in the socket member 14, which is countersunk in the gunwale, having suitable attaching means, such as screws for securing same in place.

locking plate, which slot communicates with the central opening in the locking plate. -When the pin 15 and the slot 16, are in register, the oar-lock shank may be inserted into the socket member and turned to the correct position for rowing, and in this position, the pin will engage the under face of the enlarged central portion 6, of the plate, and as the top edge of the socket member 14 is countersunk, ample room is provided for the passage of the pin, which, when the oar is operated, has bearings against the inner surface of the locking plate.

The oar lock proper is of the usual shape, adapted to be clamped around an oar, and comprises the lower arm 17, formed integral with the spindle 7, and the said arm at one end is provided with spaced ears 18, which are apertured for a pivot pin 19, which passes through the cars 18 of the arm 17 and through a central ear 20, of the locking arm 21-. The ends of said arms at this point of connection are substantially flush, when the same are in normal or closed position. The opposite or free ends of the arms 17 and 21, are connected together in the following manner.

The arm 17 is provided centrally of its edge 22, with a flange. 23, the upper face of which inclines outwardly toward the outer periphery of the said arm and is further provided with a transverse flange or latch 24. The outer or free end of the arm 21, is bifurcated to form a slot 25, adapted for the reception of the edge flange 23, of the arm 17. A. blade spring 26, is secured to the outer edge of the upper arm 21, adjacent its free end and is secured thereto by the screws 27. The spring 26, carries on its lower end the catch bar 28, adapted for engagement with the flange or latch 24, of the arm 17.

It will thus be seen that it is only necessary to lift the arm member 21, on its pivotal connection, by releasing the catch bar from the flange 24:, of the arm 17, and elevate the oar from the lock and should it be the desire to transfer the looks from one boat to another, or to remove same to prevent the theft thereof, it is only necessary to V revolve the oar lock until the pin registers with the slot in the locking plate, and lift the lock from the gunwale;

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation together with the device which I now consider the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made as are within the scope of the claim appended hereto. 7

Having thus described my invention, what I claim and desire to secure by Letters Patcut, is as follows An oar lock, comprisingin combination a spindle, a lock member formed on said spindle and forming the greater part of a circle, the ends of the lock extending above the horizontal diameter of the circle, a closing member pivoted. upon one end of the lock and shaped to close the latter, a locking tongue on the free end of the closing member and fitted to recess within the free end of the lock, an outwardly projecting latch member formed on the free end of the lock member and extending beyond the outer edge thereof, and a leaf spring secured to the closing member and extending therefrom in slightly divergent relation to'overlie its free end, and a catch on said spring adapted to engage over the tongue on said lock.

In testimony whereof, I ailix'my signature, in the presence of two witnesses.

GEORGE W. ARMSTRONG.
